This is what constables are supposed to be doing. If we don't have enough constables doing the work, we should get more constables on board (if possible). Constables are also the people who do the mechanics of the work of approving articles.
I have a slightly different take, which is that constables have two basically separate roles, one involving
behaviour, and enforcing policies etc, and the other involving access to certain technical capabilities.
I would assume that the set of people who are fitted for
both of these roles is smaller than the set of people who are suitable for just the second. Also, there are people who don't want the responsibility of the behaviour/enforcement aspect of Constables (in some cases, 'been there, done that'), but can contribute usefully in ways that need access to certain restricted tools to be able to contribute.
The 'janitor' proposal was simply trying to recognize that reality. (Indeed, we already have people who are sysops, but aren't constables - so we basically already have them, we just don't have a name for them as a class.)
I would rather not designate people with real power and authority as "janitors."
But the point is that my proposed janitors would
have no 'power' or 'authority', as those words are conventionally thought of - precisely as real janitors, who although they have keys to all the offices, almost nobody would describe as having 'power' or 'authority'.
This is interesting and does help clarify your view, but I am still not persuaded that you've set my point aside. The
right in the system to delete pages, for example, is tantamount to the
power to delete pages. There is no way to circumscribe the power technically--only socially. So, if you have that power, it is a relatively fine point for us to say that you do or do not have the authority to delete a page
if it is abusive (in some way). Once we identify a class of people who has a technical right without the social right, we must keep a watch over them. And
that in turn means extra layers of complexity, rules, and bureaucracy. The
social system becomes more complex. It's a principle of social community design that you do not multiply social roles, or socially-enforced (as opposed to technically-enforced) rules, unnecessarily. To do so is both inefficient and carries the inherent potential of abuse of authority.
This is also why we never, despite considering it several times, established a special class of copyeditors, either.
